I wouldn't use them on a keyed shaft (i.e the output) but they work great when bolted to a wheel. Use the hubbed ones though.

Like maybe McMaster-Carr p/n 60425K52?

These are pricy compared to IFI but the assembly will be less complex because you won't need spacers. Also as Salik points out nylon is easy to drill -- you could just clamp on the "kit" sprocket and use it as a guide. And as others have attested, McMaster (almost always) delivers fast.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
